Quick answer: Fastening may change alignment, clearance or bearing restraint. Check the assembled geometry and approved fastening condition.
Why can tightening the housing alter return?
A spring can operate correctly in an open housing and bind when closed. The test should represent the final assembly. Do not loosen fasteners as a production workaround without reviewing retention and structural requirements.
A practical verification method
Measure motion before and after the specified closure sequence and inspect which clearance or shaft position changes.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Measure motion before and after the specified closure sequence and inspect which clearance or shaft position changes. | Resolve the specific question before approval |
Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
